Gjirokastër Castle (Kalaja e Gjirokastrës)

Gjirokastër Castle (Albanian: Kalaja e Gjirokastrës) is a castle in Gjirokastër, Albania (historically known as Argyrokastro, a name then applied also to the castle).

The castle dominates the town and overlooks the strategically important route along the river valley. It is open to visitors and contains a military museum featuring captured artillery and memorabilia of the Communist resistance against German occupation, as well as a captured United States Air Force plane to commemorate the Communist regime's struggle against the "imperialist" western powers.

The citadel has existed in various forms since before the 12th century. Extensive renovations and a westward addition was added by Ali Pasha of Tepelene after 1812. The government of King Zog expanded the castle prison in 1932.

Today it possesses five towers and houses, the new Gjirokaster Museum, a clock tower, a church, a cistern, the stage of the National Folk Festival, and many other points of interest.

The castle's prison was used extensively by Zog's government and housed political prisoners during the Communist regime.
